SHEET-METAL BUILDING.

Application filed April 30,1921. Serial a... 465,682.

To all whom it may concern:

Be it known that we, HENRY Bnonnow and JACOB SOHAFFNER, citizens of the United States, and residents of Milwaukee,

in the county of Milwaukee and State .of Wisconsin, have invented new and useful Improvements in Sheet-Metal Buildings, of

I particularly defined by claim at the conclusion hereof.

The drawing shows a transverse sectional I view through panellingembodying the invention.

The panels 2, which may be used for the sides or roof of a sheet metal building, each have a body portion 3, a Z portion at one edge and an L-shaped portion at its other edge. The 2 portion of the panel is formed by bending back a part 1 of the plate forming the panel upon the body portion, then bending out an L-shaped flange formed by the flangeportions 5 and 6. The L-shaped portion-at the other edge of the panel is formed by. the flanges? and 8 bent from the plate and a hook-shaped edge. 9 is formed on the outer edge of the flange 8. These edges thus formed extend lengthwise of the panel and the Z-shaped edge of one panel interlocks with the body portion and L-shaped. edge. of the adjacent.

anel to forma strong weatherproof joint. Vhile the joint above described permits of assembling the panels by sliding one down upon the other, it also provides a much quicker and easier assembly of the panels by avoiding the necessity for raising one above the other, since the flange 6 of one panel may be inserted in the longitudinally extending hook 9 and the panel with this flange 6 is-then swung directly into place to bring the parts forming the joint into abutting relation/ It will be noted that the reinforced edge 10 formed by extend ng the part 4 back on the body of the panel abuts against the body portion of the ad acent panel and the Ithree thick:-

nesses of metal thus provided enables rivets or other fastening means to be passed through the panels to secure them to a metal frame 11 without danger of tearing out the sheet metal.

At the corners of the building we provide panels 12 and 13. The panel 12 on one side of the corner has a Z-shaped edge 12 similar to the panel 2, and interlocking with the L-shaped edge of one of the panels 2 and outer edge of said panel 12 is formed by an L-shaped flange formed by'the flange portions 14 and 15. The panel 13 has a corner flange 16 having a hook-shaped edge 17. The L-shaped edge of the panel 12 and the hooked flange 16.0f the panel 13 slidably interlocks to form the corner joint with the flange portion 1 1 of the panel 12 abutting the body portion of the panel 13. The panel 13 may be formed to provide a door jamb 18 reinforced by a frame member 19, as shown in the drawing, or it may be provided with a Z-shaped edge similar.

to that used on the panel 12 for connection "with the L-shaped edge of another side panel 2. This corner construction also provides a strong interlocked weatherproof joint between the corner panels 12 and 13.

What we claim as our invention is: Panels for siding or roofing of a sheet metal building each comprising a body por: tion, a part extending back on the body portion and outwardly in the form of an L-shaped flange to form a reinforced Z- shaped edge at one side of the body portion, and a part on the other side of the body portion extending outwardly 1n the form of an L-shaped flange with a backwardly extending hook-shaped ed e, the outer flange of the Z-sha ed edge 0 one anel adapted to be hooked then swung to bring the parts forming the joint between the panels into abutting relation.

In testimony whereof, we ailix our signatures.
